実験手順
The phthalimide compound (1.65 grams) (Scheme C, Compound C2) was suspended in ethanol (100 mL). Hydrazine hydrate (1 mL) was added and the reaction was stirred at reflux for 2 hours before being cooled to ambient temperature. The mix was then filtered and the filtrate was evaporated. The crude solid was dissolved in dichloromethane, then sequentially washed with 1 N potassium hydroxide and water. The organic layer was then evaporated to give 3-[[4-(4-chlorophenyl)-2-thiazolyl]methoxy]benzenemethanamine Compound 11. Mp 117–118.5° C.; MS 331 (MH+); 1HNMR (CDCl3) δ 7.85 (d, 2H), 7.50 (s, 1H), 7.40 (d, 2H), 5.43 (s, 2H), 3.86 (s, 2H).
